Downgrading MS Office Visio & Project 2010/13 from Professional to Standard for multiple users

Note, I have KMS server already running so I assume that I can use the correct MAK key to change the serial number in all Users who use non-standard version.

Scott, what about Visio and Project 2010/13 ?

Same thing.  Going to require a removal and reinstallation.

Yes I'm using MAK MASQ.

So how do I execute the batch file:

@echo off

if "%PROCESSOR_ARCHITECTURE%"=="x86" if "%PROCESSOR_ARCHITEW6432%"=="" goto x86 
set ProgramFilesPath=%ProgramFiles(x86)% 
goto OSPP

:x86 
set ProgramFilesPath=%ProgramFiles%

:OSPP 
reg query HKLM\Software\Microsoft\Office\14.0\Common\OSPPRUNONCE 
if %errorlevel%==1 (goto RUN) else (goto END)

:RUN 
C:\Windows\system32\cscript.exe "%ProgramFilesPath%\Microsoft Office\Office14\ospp.vbs" /inpkey:767HD-QGMWX-8QTDB-9G3R2-KHFGJ 
C:\Windows\system32\cscript.exe "%ProgramFilesPath%\Microsoft Office\Office14\ospp.vbs" /act 
REG ADD "HKLM\Software\Microsoft\Office\14.0\Common\OSPPRUNONCE"

:END 
Exit

Select allOpen in new window

Above to those users in the office ?
what's involved ?

This is where you hit the edge of my skill set!  I'm OK on licensing but make a pretty poor script writer - I'll see if I can enlist the help of someone who knows...

Yes please MASQ,
That'd be greatly appreciated.

OK, the batch script is working like a charm,

However I was just thinking that if I remove the Office Visio & Project 2010 Premium/professional Editon and then put in the Standard Edition, does the Application will be validated or activated as Standard Edition without me forcing it with the batch Script ?

or it will have to wait until 180 days re activation period again ?

As per: https://technet.microsoft.com/en-us/library/ee624358(v=office.14).aspx

KMS activation renewal

KMS activations are valid for 180 days. This is called the activation validity interval. To remain activated, KMS clients must renew their activation by connecting to the KMS host at least one time every 180 days. By default, KMS client computers attempt to renew their activation every seven days. After a client’s activation is renewed, the activation validity interval begins again.

Is it possible to insert the KMS key for Visio and Project 2010 Standard Edition after removing the other version ?

and then hping that in the next week all installation is becoming Standard Edition without causing issue to the end users companywide ?

ok, so what about if the Office Visio/Project is installed using MAK instead of KMS ?

somehow the batch script doesn't work, so I guess there is no other choice apart from manually reinstalling it ?

Thanks The solution works for Visio but not forMS Project.
